Help-- S0108 GLCD Not Initializing

[K1JOS]

I am new to Arduino but have some basic-moderate experience programming PIC's. I have a Uno and a 128x64 generic (WIDE-HK) KS0108 3 chip monochrome LCD (it matches the Pinout B shown in the GLCD support docs). I extracted the GLCD version 3 library (keeping its sub folder structure same) into the Arduino library folder. I then uploaded to the Uno the GLCDdiags and opened the Serial Monitor. I get the following initialization error shown below. I double checked the harness wiring from the display to the UNO and then used a DVM to confirm the continuity from each display pin to the corresponding Uno pin to make sure no wire issues. The display lights and shows 4 large vertical sections each having an alternating color (1st=blue, 2nd=white, 3rd=blue, 4th=white) and within each vertical band there is random pixels on and off. I hit reset a few times but returns with same pattern and error on Serial Monitor. I also tried switching CSEL1 and CSEL2 but this gave me no pixels. Any advice/help appreciated, thanks Jerry

I said the WIDE-HK is a 3 chip but I am not sure as the IC's are covered with black epoxy. It has three IC's. two being identical in size and third larger.

Have you checked the shop where you got the display for info on using it with the Arduino? Do you have a link to the datasheet?
